In the past, the development of such a database produced no real pay-back on investment until many years, and millions of dollars had been committed. The Land Administration Domain Model (LADM) (ISO-TC211 2012) provides...

Connectivity in the regular polytope representation

In order to be able to draw inferences about real world phenomena from a representation expressed in a digital computer, it is essential that the representation should have a rigorously correct algebraic structure. It is also desirable that the underlying algebra be familiar, and provide a close modelling of those phenomena. The fundamental...
